A friend asks you a question after your biology class. "What is genetic engineering?" You answer,

Genetic engineering is moving genes from one organism to another.

Gentetic engineering in agriculture has been employed to make crops

resistent to pests, resistent to certain herbicides, and more nutritious.

Crop plants are made resistent to insect pests by

inserting a gene from bacteria that secrete Bt into the plant.

Glyphosate, the active ingredient in the herbicide RoundUp, is a good choice for engineering plants to be resistent to because,

it is a powerful herbicide, it is readily biodegradable, and humans are not affected by it.

of what benefit is the metallothionin gene that is inserted into golden rice genome?

to supply extra sulfur to increase iron uptake.

what is incorrect about genetically modified crops

they are not allowed to be grown in the U.S.

Which is incorrect about restriction enzymes?

hey are found in bacteria and eukaryotes.

scientists in Scotland figured out a novel method to clone cells successfully. It involved

using an egg and a nucleus that were at the same stage of the cell cycle.

genomic imprinting works by

blocking the cell's ability to read certain genes.

a clear distinction between therapeutic cloning and reproductive cloning is that

therapeutic cloning involves the eventual destruction of the of the embryo, whereas reproductive cloning doesn't.
